GENERAL INSTRUCTIONS

• Please study these instructions carefully before you remove your stock camshaft. If you have any questions or problems, do not hesitate to con-

tact our Technical Hotline at: 1-800-416-8628.

• These instructions are designed to give general installation guidelines. A complete step-by-step procedure manual would require many pages. If

you are a novice or just learning to work on automotive engines, we recommend consulting either Chilton or Motors automotive manuals before
you begin. You may also wish to contact an experienced mechanic. Be advised: improper installation may result in LOW MILEAGE, POOR PERFOR-
MANCE, COSTLY REINSTALLATION AND EVEN ENGINE DAMAGE. Installing a camshaft is a complex procedure. Please follow these instructions
carefully. Failure to do so may void your warranty.

• Before you begin the removal and installation process, please examine the kit for possible shipping damage. If the camshaft is damaged, contact

your dealer immediately. Also, make sure you have all the recommended tools and parts as listed below. As you read through these instructions
the first time, use the preparation checklist to check off the exact items you will need.

• Performer-Plus camshafts are ground specifically for use with the corresponding Performer manifold #3701 (#3706 for 1987 engines). Both are

dyno-matched and street proven to work as a team; especially when matched with the Edelbrock Micro Plus ignition computer and Edelbrock
Tubular Exhaust Systems. However, the Performer camshaft package may be used by itself.
